Its horrible keyboard response is killing any wish to actually use it standing in front of the machine. Biggest problem is that it ignores keyup events, so the auto-repeat kicks in, and if its the backspace that sticks, half a line or more of a hal file is erased and the only thing you can do is kill the editor w/o a save and start over. A reboot will often fix it, for half a day maybe, or it could make it so bad you have to use the power switch to reboot it.
I now have on this desk, and up-board with and intel atom cpu, 2G of ram, and 16Gm of eMMC memory built in. About $125 shipped by fedex from the Netherlands. And a fresh copy of our hybrid install iso. And I have a terabyte backup disk by seagate, $65 with taxes at Staples, powered by a stock usb-2 cable. Works nice That atom is now a quad core, running at about the same speed as the pair of D525MW hearted machines I've been running lcnc on for several years and happy as a pig in cool mud over how they've worked. If this one will work as well I'll be a happy camper. I just joined their forum because I need to get 2 things, first being the drill pattern it bolts to, and 2nd, is the gpio layout a clone of the pi's 40 pin header. In which case there may be a measureable chance of hm2_rpspi.so spi driver actually driving the SPI interface to a 7i90. On an intel powered board. Yeah, I dream big. :) > > ---------------------------------------------------------------------- >-------- Check out the vibrant tech community on one of the world's > most engaging tech sites, Slashdot.org! http://sdm.link/slashdot > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
